HIGH-SPEED CYLINDER PRINTING PBESS.

may comer n: Be it known that I, OSKAR 'Fmmmos, a' citizen of Deutsches Reich, and residin at 34 Petrini Street, Wurzburg Bavaria, ermany, have invented certain new and useful Improvements in High-Speed Cylinder Printing Presses,'of which the following is a specification. J F This invention relates to high speed cyl nder printing presses, namely to those with the printing cylinder rotating-always in the same direction and with, the printed sheets discharged at the front of the'machlne.

The object of the invention is to render 1t for the machine minder whilst standing straight .in front ofthe machine in an easy attitude, to watch the'printedsheet which is .directly in front of him,

with "the greatest s'p "without leaving 111s and the screws for regulating the delivery of f ink which are also directly in front of him, and

to adjust the said screws.

The invention has for its furtherob ect to make it possible .for the machine minder to carry out, without any danger and effort, eed and reliability and throughout the whole width of the printing .are avoided, and the quality-of the product and to eliminate at once during the running ofthe machine any trouble in the delivery of ink that becomes noticeable. Wrong positions of the screwsfor regulating the delivery of ink are obviated as the longitudinal stri sof'the sheet and the screws regulating t e delivery of ink td these longitudinal strips are situated in the same direction before the eyesof the machine minder. In this way, mistakes in printing improved;

Thus the consumption of power of the machine is reduced owing-to the elimination of the great weight of the reciprocating distributingtable or board.

In order to obtain this and other improvements hereinafter described the duct is mounted under the delivery board, and both are arranged close to the front edge. of the machine, and the rest of the-inking apparatus 'is made so shallow that it can be a'ccommodated under the taking off device place, the regulation These'advantages are preferably obtained in an inking apparatus which does not contain any reciprocating distributing table'.

Application filed August 2; 1924. Serial No. 759,811.

without a distributing table'being preferably employed.

' The accompanying drawing shows two constructions of those parts of a well known high. speed cylinder printing press which are effected bythe invention.

- Figure 1 is a diagrammatic longitudinal section through the front part of the machine of one construction and Figure 2 a similarview of a-second con-.

struction.

In the drawing a is the delivery board and b the printing cylinder of a high speed cylinder press, always rotating in one and the same direction; d a takingfoif device of an desired construction which conveys the printed sheet in a practically horizontal direction from 'the printing cylinder to the delivery board and e is the reciprocating carriage of the machine. Thiscarriage is not provided with any distributing table. The delivery board a is arranged on the front of the machine. Under the taking-off device (Z is arranged the inking apparatus. The beginning of the inking device is con stituted by the ink duct f of'the well' known construction which is mounted under the delivery board a. Both are arranged-close to the front of the machine. The duct or roller (or vibrator) it supplies ink from the ink duct to av reliminary distributing roller r. A second duct or roller 1; in the construction shown in Figure l 'moves between the preliminary-distributing roller 7' and a fixed distributing roller 2. The roller 22 rolls over the fixed ink distributing table t backwards and forwards; it is'operated by a fork g driven by the reciprocating carriage e.

In the construction shown in Figure 2 the duct or roller or vibrator 12 travels between the preliminary distributing roller 1' and a fixed distributing roller 2' which transmits the ink'by means of a cylinder i to a second distributing roller 2" and by means of another cylinder 47a to the fixed distributing roller 2. From the distributing roller 2 the ink passes, in both constructions, to the inking rollers 90 from whence it'is taken by the .form. I r

lVhen the machine .m inder takes up his usual working position in front of the machine he can see whilst standing-normally the. printed sheets all the way from the printingcylinder over the taking-off device d and after their laying on the delivery board a, and can make surewhether the right quantity of ink is everywhere or whether single longitudinal strips of the print get too much or too little ink. Without changing his place and his position, he can eliminate then any faults in a convenient attitude by means of the regulating screws f onthe ink duct f and can always compare the position of the faulty strips of the print with the positionof those regulating screws 7" which he has to change. v

- The inking apparatus in both. const'i'uc-' tions is built so shallow that it can be acconunodatcd under the taking-off device and delivery table. In the construction shown-.

in Figure I it is a table inking device with a fixed distributing table over which rolls to and fro the duct or roller 1;. In the construction shown in Figure 2, the inking device is constituted exclusively by rollers. In the former case, it has all the advantages of the table inking devices withoutthe drawback that the reciprocation of the heavy distributing tzblc unfavorably affects the running of the machine and consumes a good deal of power. The weight of the roller '0 with the fork g is very sin 11 relatively. to that of the distributing ta le.

The invention has among others also the advantage that'the inking device at the front of the machine and the laying-0n table at the rear of the machine do not project beyond the end positions of the carriage driving frame. The machine therefore is as short as it is possible to make it with due re gard to the length of printing.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed I declare that whatI claim is 1. In a tine-color high speed cylinder printing press, the combination of astationary printing cylinder always rotating in one direction, with ataking-otf device directed towards the front of the machine, a delivery table near the front edge of the machine, an

inking device in which all themovable and ink conducting surfaces are cylind'rical'and under the taking-off device, an ink duct, said duct mounted under. the delivery table and close to the front edge of the machine and a reciprocating carriage coacting' with said printing cylinder.

2. In 'a one-color high speed cylinder press, the combination of a stationary printing cylinder always rotating in the same direction, with ,a taking-oil devite directed to-' wards the front of,tho machine, and moving the sheet substantially in 'a horizontal direction, a delivery table close to the front edge of the machine, an inking device in which all the mdvahle and ink conducting surfaces are cylindrical and'undci' the taking-off device, an ink duct, said duct mounted under the delivery table and close to the front edge 3. Ina one-color high speed cylinder printing press, the combination of a printing cylinder always rotating in the same.dire cti'on, with a taking-off device directed towards the front ot'the machine, a delivery of the machine, and a reciprocating carriage coactmg with said inking devlce and a printing cylinder.

in the same direc table close to the front. edge of the machine,

an inking device in which all the movable and ink conducting surfaces are cylindrical and, provided witha fixed distributing table under the taking-off device, an ink duct -mountcd under the delivery table and close to therfront edge of the machine, a carria e, and a duct or roller travelling to and r0 on said fixed distributing table, and a fork engaging said roller and actuated by said carriage.

In testimony whereof I have afiixed my signature. i s
